C-Arm Device Segmentation for Easier Arm Section Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing C-arm-based medical devices with two movable arm sections are cumbersome and difficult to disassemble and maintain, compromising their serviceability.
Innovation Solution
The C-arm-based device includes a C-arm component with a first and second arm section movably connected via guiding sections on a base, allowing independent disassembly and assembly of the arm sections, and a driving component to adjust the distance between them, facilitated by a drive acquisition mechanism and conversion mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the C-arm-based device includes two movable arm sections to adjust distance between radiation generator and detector, then clinical flexibility is improved, but device complexity and difficulty of disassembly increase
Solution Approach 1:
The C-arm component is segmented into a first arm section and a second arm section that can be independently disassembled and assembled. The connection component is divided into a first guiding section and a second guiding section separately disposed on the base. This segmentation allows the arm sections to be adjusted independently for clinical flexibility while simplifying maintenance through modular design.
2Ease of repair
If the arm sections are movably connected via guiding sections on base, then ease of maintenance is improved, but device complexity increases
Solution Approach 1:
The connection structure is segmented into separate guiding sections (first guiding section and second guiding section) that are independently disposed on the base. Each arm section connects to its corresponding guiding section, allowing independent disassembly and maintenance of each side without affecting the other.
Solution Approach 2:
The guiding sections serve multiple functions: they guide the movement of arm sections, provide structural support, and enable easy disassembly for maintenance. The anti-collision blocks integrated into the guiding sections provide additional protective function while maintaining the same structural element.
3Object-affected harmful factors
If anti-collision blocks are added to guiding sections, then safety is improved, but device complexity increases
Solution Approach 1:
The anti-collision blocks are merged with the guiding sections as integrated components. The anti-collision blocks are detachably disposed on the guiding sections, combining the guiding function and collision protection function into a single structural assembly, thereby providing safety without significantly increasing overall device complexity.
4Ease of operation
If driving component with conversion mechanisms is added to adjust arm section distance, then ease of operation is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The driving component uses a drive acquisition mechanism that converts rotational motion into linear movement of the arm sections. The conversion mechanisms (first drive conversion mechanism and second drive conversion mechanism) transform the rotational drive into precise linear positioning, replacing complex multi-stage mechanical systems with a more streamlined approach that maintains ease of operation while reducing overall complexity.
